EYEGLASSES.

3PECIPICATIOIforming part of Letters Patent No. 35%,317, dated December14, 1886.

Applicati n filed July 23, 1886. Serial No. 10 ,861. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE W. HASSEL LUND, of New Castle, in thecountyof West chester and State of New York, haveinvented a new anduseful Improvement in Eyeglasses, of which the following is aspecification, reference being had to the annexed drawings, forming apart thereof, in which Figure l is a side elevation. Fig. 2 is a detailsectional perspective view of one of the nose-pieces, and Fig. 3 is aperspective sectional View of the nose-spring.

Similar letters of reference indicate corresponding partsin thedifferent figures of the drawings.

The object of my invention is to provide an efficient nose-piece, thecontactsurface of which may be readily removed and replaced; ,also, toprovide a protection for the'ends of the contact-surfiices.

My invention consists in the combination, with the frames or connectingdevices of a pair of eyeglasses, of pivoted nose-pieces provided withremovable cylindrical yielding coir tact-pieces.

It also consists in a spring of peculiar form for connecting theeyeglasses.

I have shown my improvement as applied to rimlcss eyeglasses; but it isobvious that it is equally applicable to glasses having the usualframes.

To the eye-lenses A are secured bolsters B by means of clips a, formedon the bolsters and extending over the sides of the lenses, and securedby screws passing through apertures in the lenses and binding the clipsin their places.

To each clip is secured an arm, I), which ex tends a short distancearound the periphery of the lens, and is provided with a pair of ears,0, between which is pivoted the nosepiece 0. The nose-piece Cis formedof astrip of metal doubled or returned parallel to itself, one end ofthe strip being provided with a hook, d, the opposite end, 0, of thestrip being adapted to enter the hook. The arms, f g, thus formed arecurved slightly or made outwardly convex, to adapt them to the side ofthe nose. The arm f is preferably made elliptical or angular incross-section, and is provided with a shoulder, 71 near the bend of thenose-piece, and upon the arm f is placed an axially -bored yieldingcylindrical piece,

D, of cork or analogous material. The ends of the cork are made convexand provided with hemispherical or centrally-apertured caps or ferrules1, for protecting the ends of the cork andpreventing them from splittingoff from the arm f. The army, near the bend of the nose-piece, isprovided with an apertured ear,j, which is received between'the ears 0on the arm I), and swings on a pivot, 7:, which passes through one ofthe ears 0, through the ear j, and screwsinto the remaining ear 0. Thearm f is arranged to spring outwardly, so that when its end 6 is placedin the hook d it will tend to retain its position in the hook. WVhen thearm f is released from the hook d, the yielding cylindrical piece Dmaybe readily removed and replaced.

Although I have described the body of the yielding contact received onthe armf as being cylindricahldo not confine myselfto this form, as itmay have an elliptical or oval cross-section.

The bolsters B are apertured transversely in a direction parallel withthe edges of the lenses A, and are provided with binding-screws Z. Togive the curved spring E, which connects the two bolsters, the requiredelasticity, and at the same time resistance to torsion, it is formed ofa half-round wire. The ends of I the nosesprings are inserted in holesin the bolsters B and clamped therein by the binding-screws Z.

\Vhen my improvement is applied to eyeglasses having frames of the usualdescription, the ears 0 and. bolsters B will be soldered to the framesand the clips a will be omitted.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with the lenses A and devices connecting the lenses,of pivoted nosepiece 0, having curved armsf g, a fastening device,substantially as shown and described, for connecting'the free ends ofthe arms, and a yielding contact-piece placed 011 the arm f.

2. In an eyeglass frame, the combination, wit-h the yieldingcontactpiece D, of caps '13, placed on opposite ends thereof,substantially as shown and described.

3. The combination, with the bolsters of the eyeglasses, of a curvedconnecting-spring formed of a wire having a half-round crossoppositeends thereof, andacurved half-round [9 section, the said half-round wireforming a connectingspring having round ends and a highlyelastic springcapable of resisting torfiat middle part, substantially as shown andsion, substantially as shown and described. described.
